(1) Connect I-jet to the PC with IAR EWARM installed using the USB micro cable included with I-jet. This
enables the PC to automatically install the device driver.
(2) Connect I-jet to the evaluation board(ex. S5U1C31xxxTx) using the cable and adapter included with I-jet.
(see Figures 3.3.1.1)
Figure 3.3.1.1 Hardware Connection using I-jet*1
*1: Figure 3.3.1.1 shows an example when the evaluation board (S5U1C31xxxTx) works using 5V power supply
supplied from a debug probe (I-jet).
For more information on the connection of hardware with I-jet, refer to the “IAR Debugging probes User Guide”,
“S5U1C31xxxTx Manual” (listed in Table 2.2.1) as necessary.
